I'm hoping to avoid building a complex cooling system. At this point, my radiator cap is the highest point in the cooling system (by several inches). I have an overflow tank, with a return into the radiator neck (so, it's a closed system), and I'm hoping that will suffice. I have a heater, too, but the top of the core is about 8" below the top of the system, so I don't anticipate a problem there. Even my thermostat housing is a good 6" below the rad cap.
My electric fan sensor is on the back of the rad, right at the inflow hose (so, at the hottest point of the coolant), and controls an electric thermostatic control for the fan.
Anybody anticipate any problems with this?
I have a buddy who believes in building the most complex cooling systems known to man, with overflow tanks, surge tanks, fill tanks, passive temperature senders with manual overrides, etc. etc. In the end, he always gets them working, but due to their complexity, getting there can take a loooong time, with many, many revisions & seemingly endless problems.
I, on the other hand, would like to do it simpler...and lighter. Considering that the Ford Focus ZX3 (from whence my engine came) had only a simple system (which I've basically copied straight across) and aren't known to have any cooling issues, I'm hoping I've done it right...
Most don't have problems with a simple system with an overflow tank like you have.
Fan sensor should work fine there.
